* Resynchronise with Debian. Remaining changes: - Add a localechooser-data package containing lists useful for packages that create automatic installation scripts. - Always support English, unless preseeded otherwise. - Drop fallbacks for Norwegian Bokmål and Nynorsk. - Simplify use of locale-gen using the new command-line argument facility in Ubuntu's locales package. - Add encoding field to languagelist file and use the full SUPPORTED file rather than SUPPORTED-short. - If the language question was already marked as seen and the answer didn't change, then don't recalculate the locale. - If OVERRIDE_SHOW_ALL_LANGUAGES is set in the environment, display all languages regardless of frontend. - Allow preseeding of debian-installer/language. - Install kbd rather than console-tools. Remove configuration file changes that: (a) modify a dpkg-handled conffile and so are policy violations; (b) are partly composed of workarounds for console-tools bugs not present in kbd; (c) are superseded by console-setup anyway.
